Water levels in caves may rise very quickly during rain and thunderstorms. Always check the expected weather conditions before entering any of the caves. If rain is predicted, consider putting off your cave trip till another day.

The ground in the cave can be slippery, so take care, wear sturdy shoes and take a torch

The oil on our skin alters the way stalactites and stalagmites grow and can even change the colour of the rock, so please look but don’t touch

The best way to explore the mysterious Arch Cave is on the Arch loop track. This easy walk starts and finishes at the Borenore picnic area, simply cross the footbridge from the picnic area and it’s just a short walk to the cave.

Take your time along the walk to check out the rock formations, they are quite striking close up and feature black, orange and yellow striped markings. Once you’re inside the caves, go slow to let your eyes adjust, or flick on your torch.

Look to the roof of the cave for the stalactites that cling tightly and to the stalagmites that grow upwards from the ground. Do you know what happens when the stalactites and stalagmites meet? They become a column; see how many you can count.

Spend as long as you like in the cave, from here, it’s just an easy walk back through woodland to the picnic area.
